. In the figure below, parallel lines m and n are intersected by the transversal t. Based on the information given in the figure, find x.
m=127

49.6 is what i think it is.

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
